Reporting Service - SSRS subscription cant edit/ add and report not send out

One of my report not send out from subscription.
I click on the report manually and report can be come out without any issue.


I login into reporting service and found out  SSRS subscription cant edit/ add and report not send out.

It give the below message :

"Reporting sererver -subscription can't be created or edited because the credentials used to run the report are not stored, or if a linked report, the link is no longer valid"


I fix two item in the report
1. link to sub-report which is not available
2. data source have invalid server name, and the data source is not been use in the report. I re-point to the correct data source

After I fixed the above 2 items, email subscription working again.

Read ALL SQL deadlock information from Extended Events Log

How to read single deadlock information from extend event log

Read SQL deadlock information from Extended Events Log

So if we want to read all deadlock information which log into extend event,

how I doing ?

1. Run the below query in ssms to retrieve deadlock information from extend event.

Remember to change the folder name based on sqlversion

 "FROM sys.fn_xe_file_target_read_file('D:\MSSQL11.MSSQLSERVER\MSSQL"

 2. Copy the result into notepad and save

3. Open the notepad from excel with delimited "|"

4. All deadlock information will show in excel worksheet

Hyper-V Virtual Server connect to internet using WIFI

Below from my own reference, and I direct copy direct from the below URL
 how-to-set-a-hyper-v-virtual-machine-to-use-my-wi-fi-connection  -answered Jul 9 '14 at 20:32 byTravis

Below for my reference :

1. Launch Hyper-V Manager from your App Menu
2. In the Actions area in right-hand navigation, click “Virtual Switch Manager”
3. When the Virtual Switch Manager window opens, select “New virtual network switch” on the left, select “Internal” on the right, and then click the “Create Virtual Switch” button
4. Give the new switch a name like “Virtual WLAN” and click “OK”
5. In Windows 8 sys tray, right-click on the wireless icon and click on “Open Network and Sharing Center.” You will see the new Unidentified Network connected to the vEthernet (Virtual WLAN) adapter.
6. Back in Hyper-V Manager, select your VM (make sure it is turned off) and on the lower left side, click “Settings”
7. The Settings window will default to Add New Hardware, select “Legacy Network Adapter” and click “Add”
8. In the Legacy Adapter details, select the “Virtual WLAN” adapter we configured earlier and click “OK”
9. Go back to Windows 8’s Network and Sharing Center and click on the “Wi-Fi” link (or the name of your laptop’s wireless adapter) listed in the Connections In the adapter status window, click “Properties”
10. In the Properties window, click the Sharing tab, check the “Allow other network users…” box, select “vEthernet (Virtual WLAN)” (or the name of your wireless adapter), and click “OK” to close the window
11. Click Close to exit the Wi-Fi status window
    
12. To confirm you have it setup correctly, click on the “Change adapter settings” link. You should see the word Shared beside your wireless connection.

After setup all the above,  windows server in hyper-v able connect using WIFI

 Ubuntu using HyperV;
I still no manage to get my wifi connect to internet

I do the below :
sudo  ifconfig -a    -> cant get IP
sudo lshw -class network  -> it show network disabled
ls /sys/class/net   -> show ubuntu internet interfce name; example :   enpp1203

enabled network interface enpp1203
sudo dhclient enpp1203

verify:
sudo lshw -class network
We can see the "disabled" word no longer there

after do the above step, i can connect to internet from Ubuntu inside hyperv using my wifi

Read SQL deadlock information from Extended Events Log

Analysis Deadlock from Extended Event Log is difficult.
It will give result in XML Code


Do google and found out script to convert the XML code to table format so we can easy analysis the deadlock information


SQLServerCentral.com - Reading Deadlock Trace
http://www.sqlservercentral.com/Forums/Topic955603-360-1.aspx


we paste the xml format get from the extended event log;
1) SSMS- >Servername->Management->Extended Events-> Session-> system_health->Package0.event_file
2) Right click -> View Target data
3) filter with xml_deadlock_report
4) in the row return with xml_deadlock_report, click on detail window -> values
    xml data will be appear in another window
5) copy the deadlock graph xml data and add at the start of xml file and to the end of the xml data
6) pass the xml into "put your deadlock graph here"
http://www.sqlservercentral.com/Forums/Topic955603-360-1.aspx

SQL Reporting database (SSRS) moving/migration- note

Back Up and Restore Reporting Services Encryption Keys An important part of report server configuration is creating a backup copy of the symmetric key used for encrypting sensitive information. A backup copy of the key is required for many routine operations, and enables you to reuse an existing report server database in a new installation.

refer to the above link for how to back up and restore reporting services encryption keys.

Moving the Report Server Databases

Both the reportserver and reportservertempdb databases must be moved or copied together

• Schedules will be recreated the first time that you restart the Report Server service.
• SQL Server Agent jobs that are used to trigger a schedule will be recreated on the new database instance. You do not have to move the jobs to the new computer, but you might want to delete jobs on the computer that will no longer be used.
• Subscriptions, cached reports, and snapshots are preserved in the moved database. If a snapshot is not picking up refreshed data after the database is moved, clear the snapshot options in Report Manager, click Apply to save your changes, re-create the schedule, and click Apply again to save your changes.
• Temporary report and user session data that is stored in reportservertempdb are persisted when you move that database.

 refer to the above link for more information

Create the RSExecRole

Information from the article
Reporting Services uses a predefined database role called RSExecRole to grant report server permissions to the report server database. The RSExecRole role is created automatically with the report server database. As a rule, you should never modify it or assign other users to the role. However, when you move a report server database to a new or different SQL Server Database Engine, must re-create the role in the Master and MSDB system databases.

The article has instruction how to re-create the role in the Master and MSDB system databases using SSMS gui

The below scripts copy from the above article for my reference

use [master]
GRANT EXECUTE ON [sys].[xp_sqlagent_enum_jobs] TO [RSExecRole]
GRANT EXECUTE ON [sys].[xp_sqlagent_is_starting] TO [RSExecRole]
GRANT EXECUTE ON [sys].[xp_sqlagent_notify] TO [RSExecRole]

GRANT EXECUTE ON [dbo].[sp_add_jobschedule] TO [RSExecRole]

Sharepoint in SQL AGL intermittent timeout

Quote:
Intermittent, unusually high latency might occur when you use availability groups that have replicas that are deployed on multiple subnets.
As a best practice, connections to SharePoint availability groups in a multi-subnet environment should configure specifyMultiSubnetFailover=True to avoid issues caused by high network latency. For more information, see Supporting Availability Group Multi-Subnet Failovers.



Below should run in Sharepoint application server each time create / recreate sharepoint site to make sure multisubnetfailover keyword in add into sharepoint connection string

$dbs = Get-SPDatabase | ?{$_.MultiSubnetFailover -ne $true}
     foreach ($db in $dbs)
     {
          $db.MultiSubnetFailover = $true
           $db.Update()
     }
